This invention relates generally to printing presses and vmoreparticularly, to a certain new and useful improvement in printingpresses of multi-color type.

My new press is especially, though not exclusively, adapted for use inprinting multicolored impressions or so-called dies on hat-` linings andthe like, andthe prime object of my invention is' to provide a printingpress llo of the type stated by means of which successivelycomplementary impressions forming or constituting the particular die maybe rapidly and conveniently made on the lining or other printablematerial. l

My invention has for a further object the provision of a printing-pressof the type and for the purpose stated which maybe economicallyconstructed, which is sturdy, strong, and durable, which is convenientlyoperable, and which is efficient in the performance of its intendedfunctions.

And with the above and other objects in view, my invention resides inthe novel features of form, construction, arrangement, and combinationof parts hereinafter described and pointed out in the claims. y

Referring now more in detail and by reference characters to thedrawings, which illustrate a preferred embodiment of my invention, themain frame of the machine preferably includes a pair of spaced rigid A-rames or floor stands 1, l, fixed upon which by suitable fasteningelements 2, is a horizontally disposed bed or table-member A. In thepresent machine, the platefA preferably comprises a main longitudinalinverted channel-shaped member 3 extending at each of its opposite endsbeyond the respective A-frames 1, 1, for supporting attachment theretoof pairs of upstanding parallel laterally spaced rigid guide-rods 4, 4,Whose opposite endportions are preferably reduced 1n diameter and snuglyfitted at their lower extremities into the member 3 and at their upperextremities into a longitudinal channel-shaped arch-piece or beam 5disposed horizontally opposite the table-member 3.

Suitable fastening elements or nuts 6, 6,

threadedly engage the respective reduced ends of the guide-rods 4, 4,and abut the members 3 and 5 for firmly drawing the shoulders of thereduced end-portions of the rods 4 thereupon to form a rigidlongitudinal upstanding` rectangular frame B, in which is adapted forvertical reciprocation a pressurehead C carrying an aligned plurality ofcomplementary impression-blocks H, presently described. Preferablyintegrally united to the table-member 3 for front and rear preisentation from the rectangular frame B, is a pair of transverse-parallelcarriage-supports or' `lli-beams 7, whose depending stems are conjoinedto the flanges of the member 3 Figure 5) for the purpose of strength andrigidity. The outside anges of the respective L{1w-beams 7, i',intermediateiy extended to :form ings 7, T, seated on suitable pads orsupporting members provided on the respective -frames i, i, and securedthereto by the astening elements 2, fr.

inresented upwardly from each the Y- beams i?, "I, is a rib 8, Figure o,whose upper surface is provided with an inverted ii-shaped ire dependingV-shaped or faced guide-members 10, 10, each slidably coacting with oneof the ways 9, 9, for supporting the carriage D in its reciprocatorymovements through the frame B and into the printing lane of theimpression-blocks H, as will shortly be described. Each guide-member 10is provided with a laterally presented an lar face 11 sldably coactingwith a retaimng gib 12 mounted on the respective ribs 8, 8, for holdingthe carriage D on the ways 9.

Disposed longitudinally of the machine on.

the carriage D, is a pair of parallel flat ways 13, 13', Figure 3, oneor the rear way 13 having an integrally formed upstanding wall or rib14, and the other or forward way 13' having a detachable rib 14', theways thus formed being slidably engaged by a laterally presented bottomanged portion 15 of a platenblock E for translation thereof on thecarriage D from side to side of the machine parallel with the axis ofthe presser-head C and its carried impression blocks H, for purposessoon appearing.

The laten-block E preferably includes an upstan ing rigid body 16 ofsuitable shape and conformation for supporting the article to beprinted, as a hat-lining 17 of textile ma,- terial, with which themachine is particularly adapted for employment. On the upwardlypresented face of the block 16, is preferably dis osed' a mat ofresilient material or socal ed blanket 16', on which the printable partof the hat lining 17 is placed, as will presently more fully appear.

At its opposite ends, the carriage D has upstandin ugs 18, 18, eachhaving adjustably threade therethrough a stop-member or bolt 19, whosehead, presented inwardly of the -carriage, is ximpinged by theplaten-block E at the opposite extremities of its movement foradjustably limiting the cross-travel thereof on the carriage D. lThebolts 19 are frictionall locked 'in adjusted posit-ion by means of loc-nuts 2O threaded to the outer ends of the bolts and abutting therespective lugs 18, 18.

At one or more intermediate portions of the carriage D, a latch-bolt 21,Figure 3,

Xslidable through a suitable aperture 22 in the detachable rib 14', istensionally presented -by a spring 23 over the way 13' into the path ofthe platen E, the latch-bolt 21 having an upstanding pin v24 working ina suitably provided slot 25 in the rib 14' for limiting the recirocations of the bolt, which may be manu y operated for releasingmovements by grasping a forwardly disposed depending handle 26. One suchlatch-bolt 21 is shown 1n the present embodiment, the latch-bolt 21co-operatmg with the platen E for determining an intermediate printingposition thereof, so that,l as shown, the press may be' employed toapply three colors ory impressions successively on the printablematerial 17 placed on the platen E for that purpose, as will presentlyappear; but I may here state that the bolts 19 and latch 21 permit theselective location of the platen opposite the respective im ressionblocks H for printing re istration t erewith.

cured by suitable fastenin elements or studs 24', 24', Figure 3, to t eoppositely extended ends of the rear rib 14, are rearwardly presentedsupporting members or arms 25', 25', each carrying-an upstandingroll-head or bracket 26', which are vertically adjustable in anysuitable manner; preferably, however, I employ for such purpose a bolt27, Figure 1, passed through the arm 25 and workino| in a slot 28 in thelower end of a depending leg 29 of the roll-head 26', whereby the samemay be adjustably clamped on the arm 25. Each roll-head 26' is forked,as shown, to rovide a pair of vertical parallel spaced guide-slots 30,30, opening through the upper side of the head, and y closed thereat bya horizontal member 31 secured by suitable fastening elements or screws32 to the head.

Slidable in each guide-slot 30, and ver#` tically adjustable therein bymeans of screws 33, 33, presented into the slot, one upwardly from thelower side thereof and the other downwardly from the member 31, is abearing-block 34, each respective pair of bearingblocks 34, 34, havingjournaled therein an inking-roll 35, Figure 3, constructed of amaterialand in a manner suitable for the urpose intended, as well knownto those skilled in the art. In the embodiment shown, two parallelinking-rolls 35, 35, are provided, althou h more or less than two may beprovide at the option of the person constructing the machine, the rolls35, 35, being ar-. ranged with their axis of rotation arallel with, butmovable with the carriage transversely of, the axis of alignment of theimpression-blocks H.

Intermediate its ends, the rear rib 14 is formed with an anglecross-section, the outstanding leg 37 thereof being on the lower Side ofthe rib and provided with a plurality of`aligned longitudinal slots 38,38, for a purpose soon appearing. Where the anglesection of the rib 14joins the end-portions thereof, the inner wall of the upstanding leg ofthe angle is curved rearwardly, as shown at 39, 39, forming oppositelydisposed approximately semi-circular recesses in each of which is seateda post 40, Fi res 3 and 4, havin secured to its upper en ,by a suitablefastening element or screw 41, a rearwardly presented preferablyhorizontally disposed ratchet-support or arm 42, whose rear'free, endhas suitably pivoted thereto a swingable inking-disc ratchet or finger43 preferably counterweighted by an integrally formed rearward extension44, so that the linger 43 tends by its own weight to take its operativeposition, soon to be described. Adjustably clamped to the leg 37intermediate Aits ends and over one of the slots 38, is a post 40similarly carrying anA- arm 42, clampedto the leg 37, whereby the arm 42may be adjustably positioned longitudim nally the carriage D, that is,towards one side or the other of the machine, for a 'purpose also soonappearing. One or more arms 42 may be thus mounted intermediately thecarriageD, although in the present embodiment a total of three arms orratchet-supports, with their carried ratchet-fingers, is shown, one ateach end of the carriage and the other intermediately thereof.

Mounted on the T-beams 7 7, at the forg@ ward ends of the ways 9, 9, arestops in the form preferably of suitable upstanding members or angles45, 45, Figure 1, and at their rear ends the ways 9, 9, terminate shortof the rearvends of the respective T-beams 7, 7, which latteraxt therear of the machine,

are united by a superposed longitudinal member 46, mounted at itsopposite ends on upstanding hollow posts 47, 47, by suitable means, asbolts 48, 48, each passing through 3o an end of the member 46, theinterposed post 47, and the rear end of the T-beam therebelow. Eachhaving a depending hub 49 journaled on respective pins upstandinglyspaced 'from the member 46, Figures l and 3,

- 35 is a plurality of aligned sources of ink-supply preferablyincluding horizontally rotatable circular ink-carrying members orinkingdiscs 51, there being three such in the present embodiment, eacharranged opposite to, and preferably aligned on an axis parallel to theaxis of alignment of, the impression blocks H, for a purposeishortlyappearing, each inking-disc 51 having a circumferential series ofdepending ratchet-lugs 52 for co-operation with one of theratchet-fingers 43, whereby, as the carriage D is reciprocated, theratchets 43 will freely pass to the rear of and under the respectiveinking-discs 51, but on the forward movement of the carriage, theratchets 43 will respectively engage one of the ratchetlugs 52 therewithaligned for intermittent rotation of the inking-disc 51, so as topresent a.-

fresh inking surface to the inking-rolls 35 when the carriage D is againreciprocated.

The hiking-rolls 35, 35, it will be under- I stood, are verticallyadjustable, as described, for re lating the pressure of rolling contacto the inking rolls with the respective inking-discs on reciprocation ofthe carriage; and l may here point out that the inking- A rolls 35, 35,have a plurality of eripherallyinked areas longitudinally spacetherealong,

and it will be readily seen that bythus providlurality of such inkedareas each independent of the other, a variety of colorsv or inks may beapplied in a suitable series or arrangement on the rolls, eachcorresponding to one of the printing positions of the.

platen E, as shortly appearing.

The presser-head C is movable towards or away from the bed A andpreferably includes an inverted channel-shaped beam 53, Figures 4 and 5,having at its opposite ends cross-heads 54, 54, each suitably aperturedfor sliding engagement with, and guided by, the adjacent pair ofguiderods 4, 4, the beam 53 being normally upwardly urged towards thearch-beam 5 by springs 55, 55, each mounted on one of the guide-rods 54with their ends, respectively, abutting the framemember 3 and thesuperposed ncross-head 54.

The operating means for the. presser head C opposes the springs 55 forpressing the head C to the platen E and preferably comprises apedal-operated mechanism now tobe described. Each having its upper endthreaded for suitable fastening devices, as nuts 56, 56, for adjustableattachment to the respective cross-heads 54, 54, and disposed atopposite ends of the presser-head C, are pedal rods 57, 57, each pivotedat its lower end on one of a pair of pedal-arms 58, 58, Figure l,mounted at the opposite ends of a shaft 59 journaled in suitablebearings'provided in the lower portions of the frames l, 1, thetorwardly presented ends of the pedal-arms 58, 58, being united acrossthe front of the machine, for convenience of the operator, by apedal-bar 59'.

. Detachably mounted on the underside of the presser-beam 53, is aprinting-frame 60, Figure 5, preferably rectangular in plan, having atits opposite endsl upstanding dovetails 61, 61, slidable intocorresponding grooves 62, 62, provided in the beam 53, stop-pins 60.being provided on the frame 60 or'impinging the beam 53, Figure 4. Theprinting-drame 60 is detachably secured to the presser-beam 53 bysuitable fastening elements or studs 63, 63, passed through the beam 53for thread# edly engaging the respective dovetails 61, 61, Secured inthe printing-frame 60, in a manner-well known to those skilled in theart, is a plurality of aligned complementary/ impression-members H,whose axis of alignment is preferably disposed longitudinally of v 1 andthe latter being movedsuccessively from registration with one printingblock to another, the design intended to be printed will be built up,part by part, to form the completed impression, one form of which issuggested in Figure 7.

Threaded through, and depending from the arch-beam 5, is a pair ofstop-pins 65, 65, presented in the path of the presser-head C forimpinging the upper side of the beam 53 thereof for thus adjustablylimiting its upward movement, a suitable means, as a locknut 66, beingthreaded to each of the stop-pins for frictionally locking the same inadjusted position, Figure 5.

By suitably adjusting the stop-pins 65, 65, the presser-head C isbrought to the proper level or plane of the inking-rolls 35, 35, forregulating the pressure of rolling contact of the inking-rolls with theprinting faces of the blocks H, each inked-area on the surface of therolls contacting one of the blocks for the application thereto oftheproper color or kind of ink, according to the requirements of the designtobe printed.

My new press is particularly, -though not exclusively, adapted, as Ihave stated, for employment in the printing of designs or impressions onhat-linings, an illustrative de sign for the purpose being shown inFigure 7. As is well known, hat-linings are usually woven or otherwisesuitably prepared conformably to the shape of the hat-body into whichthey are to be fitted. The platen 'E is, therefore, preferablyconstructed in a similar sha e, in order that the lining, as 17, may laynice y thereupon, with its central printable area resting on the mat 16.As the carriage D is reciprocated on the ways 9, 9,the

platen E will be moved underthe presserhead C in a-path aligned with oneof the printing-blocks H for printing registration therewith. In theembodiment shown, there are three printing-blocks H carried by thepresser-head C, .and on'the carriage Dare means for locating rthe platenE in any one of three printing-positions opposite to, and forregistration with, one of the impression-` blocks H, the end positionsbeing determined by the impingement of the platen E with the respective'end stops 19, 19, and the intermediate position being determined bythelatchbolt 21, which normally yields to movement of the platen-block E onnmovement thereof from right to left for latching the same againstreverse movement.`

Figure 7 represents a three color impression, the colors being red,yellow, and een. For the purpose of illustration, it will e assumed thatthe backi-ground yellow is t0 be printed first, then the red ground inthe name-plate, then the green borders. The inking-discs 51 are;therefore, supplied with inks, respectively, of yellow, red, and greencolor, from right to left. When the carriage D is slidl to the rear, theinking-rolls 35,'v 35,

will take up the inks that are on the inlnngdiscs and will thus have alon 'tudinal series i ing-blocks H are disposed on the pressen head C inalignment with the respective inked areas on the rolls 35, the latter,of course, inking the respective blocks as the carriage D is movedforwardly on the machine. vEach printing block H carries that part ofthe design to be printed in the color of ink applied thereto by therolls, the blocks being complementary to each other, as will beunderstood. For impressing the yellow part of the design on thehat-lining 17, the platen E is moved to the eXtreme-right-hand of themachine, being thereby automatically aligned in its first printingposition, and when the carriage D 1s moved to the rear of the machine,the platen E will be in registration with the presser-head C under theyellow-inked printing block. The operator, applying foot-pressure on thepedal bar 59', ldepresses the presser-head C upon the platenblock E, thehat-lining 17 being printingly .engaged between the printing block H andthe mat 16. When the operator releases the pedal bar'59, thepresser-head C is automaticall returned to elevated position. Thecarriage D is then shifted forwardly of the machine and the platen lEmoved leftwise on the carriage past the latch 2l, and then brought tbear against the later for alignment with the red-inked printing block Hfor automatic alignment with the second printing position, when theforegoing operation is repeated.

Finall the platen E is moved to its extreme le -hand position forregistration with the green-inked printing block H. With the lastimpression, the complete design is impressed on the hat-lining, and Imay here point out that by my new press not only is the hat-linnigprinted in a much quicker and more economical manner that would be the.case if a separate printing press were'employedfor each color or ink tobe ap but also a further advantage obtains 1n that the registration o fthe component colored parts of the Voncethe printing blocks have beenset up 1n the machine, andthe printing positions of the platen Edetermined; hence the employment of match-marks or like means for ali'ng the printable portion of the hats lining with the respectiveprinting-blocks is eliminated.

Inasmuch as the employment of gold-leaf or foil-material is common inprinting hatlinings, a gold-leaf feeding device, well adapted for use inconnection with my press,

is shown in Figures 8 and 9. Such device includes oppositely outstandingbrackets 68, 69, on the presser-beam 53, in which are respectivelyjournaled spool-carrying shafts 70, 71, on w 'ch is to be wound aflexible design is automatically assured,

band or strip of windable material 67 having on one. side a strip ofgold-leaf and on the other side a plurality of indicia or indicating ormeasuring marks 67', for a purpose soon appearing. The shaft 7l has aknurled bead 7 2, and the bracket 69 has an indicating means or pointer7 3 for registration with the indicia 67. Outstanding from oppositesides of the printing-frame 60, are brackets 74., 74, each havingournaled therein a. roller 75.

Resilient members or springs 76 attached to the respective brackets 68,69, frictionally engage the spools on the shafts 70, 71, for tensionallystretching the band 67 therebetween. Initially, the gold-leaf carryingband 67 is wound on the shaft 70, then stretched over the rollers 75,75, across the printing face of the particular printing block H selectedfor making the gold-leaf impression, the gold-leaf carrying side of theband being downwardly presented, with the free end of the band securedto the shaft 71, in such wise that the indicia bearing side of the bandwill be visually presented to the operator. By bringing the indicia 67successively in registration or valignment with the pointer 73, apredetermined quantity of gold-leaf will be fed beneath the particularprinting-block H, the

. printing operation thereafter beingthe same as previously describedfor making an ink impression. 'lhe advantages of my gold-leaf` feedingdevice are that the gold-leaf is protected from injury while not in use,thatl is to say, when wrapped on the shaft 68, vthe leart' carrying sideof the band 67 is onthe inside of the roll; the gold-leaf is presentedfor the printing `operation in a smooth unbroken layer, the band 67being stretched just enough to prevent wrinkles in the leaf, yet -not somuch as to tear the latter; and the minimum amount of leaf is used ateach printing operation, the indicia 67 being arranged conformably'tothe amount of goldleaf required for printing,` the design. The device issimple, inexpensive, and reliable for the purposes intended.

My machine may asa whole be readily con-r structed and fulfills in everyrespect the objects stat/ed.

It is to be understood that changes and modifications in the form,construction, arrangement, and combination of the several parts of themachine may be made and substituted for those herein shown and descrlbedWithout departing from the nature and principle of my invention.
